Retekess TT117 Tour Guide System, Church Translation System Long Range 80m, Stereo, AA Battery, Translator Device for Conference (1 TX 10 RX)

I was skeptical but these are working out perfectly. We use them at church; the sound is perfect, and connecting the chanels is easy. Definitely recommend this product. Our church building was previously a movie theatre with a capacity of over 1000 with a very high ceiling. These work perfectly without interference.

I recommend

Todo se bien

We have had a few ideas of how to put this to work for us, but regardless what we land on, it has passed the testing phase. This set is awesome, allowing single transmission to multiple receivers simultaneously in real time. I didn't notice much lag or vocal drop until pushing limits on distance (over ~300 feet of wide open space) or obstructions (which it not designed for). Even at the distance, that was impressive for me and I wasn't expecting signal to penetrate walls. The design is simple and straightforward, allowing variable volume control (on both units) and channel selection, sound is crisp, mic pickup is sensitive and somewhat noise canceling, meaning it blocks wind alright. Now we just need to figure out our specific application, but once we do, these will perform.

This is a very generous kit of equipment to deck out a tour group, gathering or even other more creative uses. Being able to talk to 10 people over half a football field away is great, and you can set channels to only broadcast to certain people when needed. They seem to emphasize this as translation equipment since you could have several people talking (if you order more receivers) and only people set to the pre-agreed channel would hear each person. So you could have English as channel 1, French are channel 2, etc. up for 17. But with 1 receiver and 10 transmitters in this kit, it also works great as a simple way to keep a tour group together or run an event. Sound quality felt great, everyone could understand everything, and within a bigger building, transmission was not an issue at all. The devices are well built and easy to use. I kind of wish the transmitter and receivers were differently shaped or somehow differentiated, they're so similar it's very easy to give the transmitter to someone by accident. But that's a small matter, and I see why they chose to make the set matching. In terms of function, these are excellent and will hold up well for schools, churches or any organizations that need to talk to several people at once. And each receiver having earphones means no one needs to hear a large buzz of talking voices, very neat way to handle communication.
